I have a China brand tablet.its a BRIX 7" TOUCH SCREEN WIFI TABLET PC. is android 4.0 1 sim tablet/phone..ok how can I update its software and I can use my T-Mobile sim card in it but only to call out

SOURCE: my android tablet is "frozen". Will turn on but

has anything been deleted from it when it has been plugged into a computer or has anything been deleted from the device itself from its root directory? if not and its gone like that by itself, it could be corrupted software or a missing root file which is usually bad at first, now what i know about some tablets is if it wont work theres a recovery file usually internally but this is in some tablets only that ive read about, i also have one but havent needed to try to restore it and it can be done from an engineering mode, this is possable by pressing the power button and another button like the home button at the same time once the unit is off untill it turns back on with options, but as for some models im not sure of but i will have to look this up at some stage as i am working on tablets at this time so unless you know what you are doing i wouldnt attempt it, once i have gotten through some tablets ill be able to give a better resolution on this subject with others. the advice ive given wont work for all as pressing power and home will start different options up on different tablets and versions.

Try to do a hard reset on the tablet. Since you cannot get to the menu options, you are going to have to do it through external keys. Here is how to do a hard reset using the external keys:


1. Turn tablet off. You may need to use two hands in this process to press and hold buttons properly.
2. Turn on the tablet with power button, wait a full 2 seconds from the time the tablet starts showing the manufacturer logo, then press and hold the down Volume key. (you should not hold down the power button after it turns on and logo appears)
3. "Android Recovery" will appear on top of screen if timing is done correctly. Release volume button. (if you continue to press volume down at that message, the message will cycle through "RSD, Fastboot, and back to Android Recovery. Make sure message states Android Recovery before you go to next step). If stuck at a RSD protocol or Fast boot screen, reboot the tablet by holding power button then pressing the volume up)
4. While screen states "Android Recovery", Press volume up button, the screen will say "Entering Android recovery mode" and a few seconds later an Android robot graphic will appear alone on the screen. Release buttons
5. Hold down power button and then press the volume up key together to see the Android Recovery screen menu selections
6. Use the volume buttons to move up and down through selection in this menu
7. Using the volume down button, scroll down to "Wipe data/factory reset"
8. Tap Power hard key to select option
9. Scroll down to select "Yes, delete all user data"
10. Tap the power button to select. Wiping and formatting data will take a few minutes.
11. You will return back to the Android recovery screen menu.
12. Tap the Power button to "Reboot system now" which will power-cycle tablet and eventually power back on to the Initial Set-up / Welcome screen present when you first turned on your tablet.
